Tool to draw component diagrams

Question

I am looking for some tool to draw component diagram, something like mermaid , "a simple markdown-like script language for generating charts from text "

Sadly mermaid doesn't support component diagram

It doesn't need to draw a perfect UML component diagram, just help me draw the main components in the system and the main interactions between the main components.

Have a look at plantuml(http://plantuml.com/) and their web server for some tests (http://www.plantuml.com/plantuml/uml)

PlantUML is a component that allows to quickly write :

Sequence diagram
Usecase diagram
Class diagram
Activity diagram (here is the legacy syntax)
Component diagram
State diagram
Object diagram
Deployment diagram 
Timing diagram 

The following non-UML diagrams are also supported:

Wireframe graphical interface
Archimate diagram
Specification and Description Language (SDL)
Ditaa diagram
Gantt diagram 
MindMap diagram 
Work Breakdown Structure diagram 
Mathematic with AsciiMath or JLaTeXMath notation
